Answer:  The given statement is FALSE.

Step-by-step explanation:  We are given to check whether the following statement is true or false :

"If the dimensions of a cylinder are doubled then its volume is quadrupled."

We know that

the volume of a cylinder with radius r units and height h units is given by

V=\pi r^2h.

If the dimensions are doubled, then the new dimensions will be

R = 2r  and  H = 2h.

Therefore, the new volume will be

V'=\pi R^2H=\pi \times(2r)^2\times (2h)=8\times \pi r^2 h=8V.

Thus, the volume of the new cylinder will be 8 times the original one, not quadrupled.

So, the given statement is FALSE.

The junior varsity football team score 23 points in last Saturday's game they score the combination of seven point touchdowns in
frutty [35]

Answer:

  2 touchdowns, 3 field goals

Step-by-step explanation:

The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.

  23 is not divisible by 3, so 0 touchdowns is not a solution

  23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution

  23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution

  21 -21 = 2 is not divisible by 3, so there is only one solution.

Solve the equation.Check your solution<br><br>1.5x = 3
PIT_PIT [208]
Divide both sides by 1.5

1.5x = 3

x = 2

Check the equation by plugging in the 2.

1.5(2) = 3

3 = 3
